Shih Gong Enterprise Co., Ltd. specializes in precision plastic injection mold design and manufacturing. We provide one-stop OEM / ODM co-development, injection molding, and post-processing across headphones, optics, consumer electronics, medical devices, and sanitary ware — all under ISO 13485:2016 medical-device quality management.
We cover the full plastic-product pipeline: design optimization, tooling, injection molding, and surface finishing. Brand owners stay focused on the product; we handle the making.
Shih Gong holds "quality is designed in" as our core value, with 45 years focused on precision injection mold design and manufacturing. From the earliest mold-design phase, we apply a reverse-engineering mindset built on decades of production experience — pursuing the highest possible yield as our first principle. Because precision tooling is what makes high-quality mass production possible.
From mold development to high-efficiency injection machines to post-processing, Shih Gong vertically integrates its supplier network — committed to Designed, Tooled, and Made in Taiwan. Our work spans electronic toys, mobile communications, medical devices, headphones & audio, 3C accessories, and sanitary ware components — fulfilling orders from around the world with the speed and customization each customer's specs, quality bar, and timeline demand.
From consumer-grade earphone shells to medical-grade diagnostic components, Shih Gong applies the same precision-molding and finishing discipline to every project — only regulatory rigor and scale differ.

Meeting international quality standards isn't optional — it's how we earn the right to serve medical-device makers.
Medical Device Quality Management System, certified January 2025. Validates our capability to manufacture regulated plastic components for medical-device customers.
Four manufacturing cycles — home appliances, 3C, smartphones, wearables, and now medical devices. We've accumulated not just hours, but the kind of process intuition that only comes from past mistakes.
OEM, ODM, custom projects — we don't gatekeep. But at the feasibility stage we tell you honestly which parts of the design are buildable and which ones need rework.
Whether it's hand-drawn or a finalized STEP file, our engineering team can take it through feasibility, mold-flow analysis, and into production.
